SPECIFICATION formingpart of Letters Patent No. 411,158, dated September 17, 1889.

Application filed July 17,1888 Serial No. 280,166. (Model-l To all whom it may concern:

ie it known that I, MELoHIoR L. LUEBBEN, a citizen of the United States, residing at Sutton, in the countyof Clay and State of Nebraska, have invented certain new and useful Improvements in Hand-Stamps, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this specificatiom'in which Figure 1 represents a perspective view of a hand-stamp embodying my improvements. Fig. 2 is a similar view showing the stamp inverted and the inking-roller frame thrown back to expose the stamping-surfaces. Fig. 3 is a sectional view showing one of the numbering-wheels, the movable dies, and the mechanism for projecting and withdrawing said dies and actuating the wheel. Figs. 4: to 13, inclusive, illustrate details of constructions to be hereinafter described.

My invention relates to lw-nd-stamps employing a fixed stamping-surface and a series of rotating wheels or disks provided with removable'dat-ing or numbering dies carrying rubber or other characters; and my invention consists in the constructions and combinations of devices which I shallhcreinafter fully describe and claim.

To enable others skilled in the art to which my invention appertains to make and use the same, I will now describe a preferred construction and indicate a manner in which the same is carried out.

In the said drawings, A indicates a casing of suitable design and construction adapted to contain the working portions of my stamp, and provided at its top with a suitable handle, by which the stamp may be held and operated. The lower portion of the casing is provided with a curved face a, to which is appropriately secured a rubber or other printing surface 7), containing the name,busincss, address, or other desired matter, and the central portion of the curved face and printingsurl'ace is slotted at c for the reception of suitable dies containing dates or numbers, which may or may not be used, as desired, in connection with the subject-matter on the fixed stamping-surl'ace (1 A shaft (7- passes transversely through the casing A, with its ends projecting beyond the sides thereof, and

on these extended ends the curved arms e of the movable ink-roller frame 1 are mounted, the said arms being provided with curved slots f, and the lower portion of the frame B is curved to correspond with the curvature of the lower face of the casing, and has mounted between'its sides the inking-roller g, which is adapted to pass across the fixed printingsurface Z) and to properly ink the characters or figures thereon.

The movement of the inkro1ler frame B, by which its roller is caused to pass over the curved face of the fixed printing-surface, is produced by the action of suitable verticallyarranged plates 0 on each side of the casing,

provided with slots, through which the ends of the shafts (Z pass and are afterward secured. by nuts, as shown. The lower portions of the plates 0 are extended to form feet h, which are designed to rest upon the paperor other article to be stamped, and each plate 0 is provided with an inwardly-projecting pin 1', which passes through the curved slots f in the arms 0 and through other slots 7' in the sides of the casing, so that their inner ends may be engaged by one end of springs D, located within the casing, while the other end of said springs may be securely attached to some portion of the casing or to the shaft (1, if desired, as shown in Fig. 12.

From the description of the parts thus far enumerated it will readily be seen that in its normal position the frame 1) lower curved face of the casing and the fixed printing-surface, and thereby protects the latter from dust or injury, while the lower portions of the plat-es extend some distance below the bottom of said frame Now, in order to cause the printing-surface to impress its subject-matter upon paper or other suriucloses the 1 face, the operator places the foot portions 7:-

over the space to be stamped and then presses upon the handle. The pressure upon the latter causes the plates to move vert cally, and their pins [,actingupon the curve lwalls of the slot f, force the frame I; to one side, thereby causing the inking-rollm's to pass across and ink the characters on the rubber inking plate or surface I), the said frame being carried by the action of; the verticallymoving plates far enough in the roar of the stamp to permit the priuting-surface to come against the paper to be stamped. After the impression has been made, the operator releases the pressure upon the handle, and the springs D, acting upon the pins, force the plates downward, and they in turn cause the frame to be returned to its normal position under the curved face of the stamp.

Upon the shaft (1, and within the casin g, are mounted the series of wheels which carry the movable dies E, each of which is provided with a number, date, or other appropriate character, and each wheel comprises certain devices for proj ecting and withdrawing these dies to meet existing circumstances.

Referring now to Fig. 3 and the details illustrated in Figs. 4 to 12, inclusive, F represents a disk whose periphery is formed with a series of radial slots 1, and E indicates the dies, which are formed with or have secured to them independent numbers, dates, or other matter, the said dies being each formed with side wings 2, which pass behind one side of the disk, and with a central web or wall 3, which passes into one of the radial slots Z in the disk, the inner end of said web or wall terminating in a projection 5, which forms between itself and the main portion of the Web a recess or notch (3, in which is fitted a ring 7 (shown in Fig. 5,) whereby all the dies H'O held in their slots against disphieement, :he said ring, however, being provided with Li] opening Ir, through which the dies are proiected when desired, and by means of which new dies may be inserted should the old ones become damaged or otherwise unlit for use.

The front wall 8 of each die is extended )ver and beyond the ring 7, and the latter is )f slightly -reduced thickness for a short space upon each side of its opening, whereby L space is left between the ring and the wall 3 for the insertion of the lower end of a ver- ;ieally-moving plunger G, which is slotted, 1po11 the shaft (1, and also upon a second shaft cl, passing transversely through casing md serving as a guide for the movement of ;he plunger.

Each plunger is preferably formed with an extension or stem G, which is encircled by a spiral spring If for returning the plunger lft-OI it has been forced up, and the body of ".he plunger near its upper portion is provided with a suitable finger m, which proiects laterally through an elongated slot '11 in ;he front of the casing, so that it may be operated to withdraw the die, the said finger- ;iece when moved vertically one-eighth of an nch raising the plunger into the casing, so .hat the next impressionwill not indicate the lumber on the die. From this description it will be seen that when it is desired to use a lumber or date in connection with the subiect-matter on the fixed stamping-surface ".he operator moves the wheel by means of ;-he plunger until the desired die is in alignnent with the slot in the bottom of the easng, and then releases the finger-piece to enible the spring ll to force the plunger downward. As the plunger moves downward, its point or lower end, which projects back of the wall 8 of the die, forces the die outthrough the open side of the ring 7 and out of its radial slot in the disk F and into the slot in the center of the bottom of the casing and fixed printingsurface, the side wings 2 on the dies entering suitable grooves or guides 10, formed in the walls of said slots, whereby the die is securely held against side movement.

Immediately back of the plunger G is a plate ll, slotted at one end, so that it may straddle the shaft (1, and having its opposite end formed with a tongue 0, whose width about equals the size of the opening in the ring 7, withinwhich it moves, the said lower end of the tongue being provided with the in ward projection 17, which occupies the notch 0 in the central web of the die previously occupied by the ring 7. T us it is that when the disk F is m..ved to advance the die thelatter is carried onto the cut-away portion of the ring 7, so that its notch G will ride over the projection or spur p on the ton guc 0, and come at rest at a point where the die, the tongue 0, the point of the plunger, and the slots I; are in direct alignment, so that when said plunger is operated its point is first projected back of the front wall of thedie and then forces the die and plate ll from their positions, the die being forced through the slot 7i: and the pro:

jection 1) remaining in the notch (i to steady the die and also to draw the same upward into its slot in the disk 1 when. the plunger is again elevated.

The plate ll is provided with slots 12 and 13, and the plunger G is provided with pins 14 and 15, which move in said slots, so that when the pins strike the ends ofthe slots the further movement of the plunger causes the plate II. to move with the plunger and to proj ect or withdraw the die, as desired.

Between the plunger G and the plate ll is placed a 1c 3r or plate l1, having a long arm '1', pivoted to said plate at s, and a short arm t, against a recess t in the lower face of which the pin 14 on the plunger G strikes during its upward movement, whereby the plunger, plate ll, and the lever L are practically locked together, in which position they remain during the upward stroke of the plunger until a cam portion uon' the short arm of the lever L strikes the shaft (l and forces the lever to one side, thereby permitting the pin ll to be released from its fixed engagement with the lever L to also enable the plunger to eolnplctc its upward stroke without affecting the positions of the plate ll and lever L. ()n the succeeding downward stroke of the plunger the pin '15, which is somewhatlonger than the pin 14, whereby it may engage the disk M, rides along the inner wall of the long arm of the lever l until it strikes the short arm t at apoint near the recess i, when it begins to force the lever and its connected parts downward. The short arm of the leverT, has

IIO

also a cam-surface n, which engages the shaft (1, so that when said lever is moved downward this cam-surface it strikes the shaft, which causes the lever to turn on its pivot s, whereby the short arm will be projected immediately over the pin ll, ready to be engaged by said pin on its upward movement to again lock the plunger G, plate II, and lever L together in operative positions, as before described.

On the shaft- (Z, back of the plate II, is mounted a disk or plate M, having a cam-surface 10 and shoulder w, the said cam-surface being designed for engagement with the pin 15 on the downward stroke of the plunger, whereby the disk M is thrown forward, so that its shoulder a: will come at rest at a point near the opening in the ring 7, sothat when the projected die is drawn upward into its radial slot in thedisk the shoulder .11 will be againstthe projection on the die E. Now it will be observed that when the plungeixis moved upward it operates the plate H to retract the die, and its pin 15 strikes the part 11; of the disk M just when the die is properly seated in its slot and causes the shouldered portion of the disk M to be thrown rearward, thereby moving the die and the disk M sufficiently to bring the succeeding die on the diskin operative position beneath the plunger.

I have described but one wheel and die in defining my invention; but it will be understood that any desired number of wheels, plungers, dies, and their adjuncts may be used, and that any suitable letter, name, or characters may be formed with or secured to the dies to operate in conjunction with the lixed printing-surlace on the lower l'aceof the casing.

To operate the stamp so that it will imprint. only the letter or character on the die, project the die, as previously stated, and then bear vertically upon the handle of the stamp. Now, as the printing-face of the die projects slightly beyond the face of the fixed rubber printing-surface, it is obvious only the die will print; but if the subject-matter on the rubber plate is needed also the operator operates the stamp by rolling its curved face over the article to be stamped, when the fixed printing-surface and the projected die will operate to stamp their characters upon the article.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'1. Ina hand-stamp, an outer casinghaving a fixed printing-surface secured thereto, in combination with a series of rotating wheels within the casing, imlependent printing-dies carried by said wheels, vertically-moving plungcrsfor removing the dies from engagement with the wheels, and means for returning the dies into position, substantially as described.
